"World's oldest man dies."
I've seen this headline over the past few months several times, and it's always about a different world's oldest man. Today, I saw a headline that was something along the lines of "Woman believed to be the world's oldest dies."
Call me old fashioned (Well? I'm waiting.), but if I were asked to make a completely random guess about who was going to die soon, after my first choice pick of the obvious Amy Winehouse, I'd say that the World's Oldest Person would be a no-brainer.
